In Situ Imaging of Ferroelastic Domain Dynamics in CsPbBr3Perovskite Nanowires by Nanofocused Scanning X-ray Diffraction
The interest in metal halide perovskites has grown as impressive results have been shown in solar cells, light emitting devices, and scintillators, but this class of materials have a complex crystal structure that is only partially understood. In particular, the dynamics of the nanoscale ferroelastic domains in metal halide perovskites remains difficult to study. An ideal in situ imaging method fo
